Reclining chair



atented ha lo, 137

NT OFFICE This invention relates to furniture. This invention hasutility when incorporated in a reclining chair.

Referring to the drawing: Fig.1 is a side view of a chair embodying theinvention herein, said chair being in straight or upright position;

Fig. 2 is a view similar to Fig. 1 with the chair in tilted or recliningposition;

Fig. 3 is a plan view through the frame of the chair of Fig. 1,approximately along the line III-III, Fig. 1, looking in the directionof the arrow;

Fig. 4 is a side view of the frame of Fig. 3, parts being broken away;and i Fig. 5 is a view on the line V--V, Fig. 4, looking in thedirection of the arrow.

The invention herein comprises a chair which may be tilted from uprightto reclining position by body movement of the occupant. It may also beagain brought to straight or upright position solely by movement of theoccupant. The shift- I ing of the chair is not only easily accomplished.

in .this manner but also remains in the predetermined desired position,allowing freedom of normal movement without throwing the chair out ofthe desired position.

The chair frame comprises front rail i, outer side rails 2 and rear rail3. The side rails 2 are fixed with the front and rear rails l, 3.Upwardly extending from the forward portion of this frame are members 4,and upwardly extending from the rearward portion of the frame aremembers 5.

The members 4 provide supports for arms 6, while the members 5 providethe frame for back 1. This frame may be upholstered in any mannerdesired with the usual webbing, springs and outer covering 8 to producethe desired style or 1 motif in the piece.

Spaced inwardly from each outer rail 2 is a rail or frame member 9 fixedwith the back rail 3 and with the front rail I. The forward ends of therails 9 may be reinforced in their anchormg with the front rail 9 bymeans of blocks Ill.

Mounted by the rails 2, 8, are pins II as supports for carriers orrollers l2, there being a pair of such rollers on each side of the chairand spaced apart. The rails 2, 9, are each provided with downwardlyextending portions I 3.

Support for the chair is provided by means of a pair of generallytriangular shaped blocks M having their apices extending upwardlybetween the rollers l2; each block providing a pair of downwardly,oppositely extending divergent faces i 5, IS, in which, in the tiltingof the chair, these faces provide tracks along which the rollers mayshift. These downwardly diverging faces may be treated with a lubricantsuch as graphite to form a wear-resistant surface against normal wear 5of the rollers thereupon and also providing a smooth surface for freemovement of the rollers.

The angular extent of such faces may vary and, as herein shown, therearwardly extending faces l6 have a sharper or greater downwardly l0angular extent than the forward faces !5. The weight of the chair, ascarried by this support, is so distributed that, by this difierentangularity, smooth action may be obtained; while in chairs havingvarious distributions of weight, these faces 15 may be so disposed as togive a nicety of balance to the chair.

Mounted in faces iii are pins ll against which the forward roller l2 mayabut in limiting the backward or reclining position of the chair, whilethe forward extent may be limited by legs 88 contacting the chairsupporting surface l9. The portions I3 of the side rails extenddownwardly to sheath the blocks It to a major extent in order to guardagainst side sway or side rocking of the supports. The chair may bemoved from place to place without the blocks l4 dropping out itherefrom, in that pins 20 laterally extend from adjacent the apices ofthe blocks over cut-out portions 2| of outer side rails 2. The cut-outportions 2 I are in the region of movement of the rails 2 as to thepins, and as the chair is picked up, the pins 20 engage the upper face22 of these cut-out regions and are lifted with the chair. In assemblingthe chair parts, these pins 20 may be placed in the blocks and as thecovering 8 is placed over the frame, the pins 20 are thereby preventedfrom removal outwardly, while the side rails 9 prevent removal inwardlytoward the under side of the chair.

The angular extent of the faces l5, I6, with their intersections orsupporting member apices disposed between the rollers, may be gagedaccording to the size and weight of the chair so that an evendistribution of weight is had on 45 a line approximately verticalthrough the supports or blocks. It takes but slight forward or. backwardthrusting of the body of an occupant to. cause the chair to assume areclining position or to be brought upward to an upright position, 50and the extent of recline is sufficient for comfort .without strain. 7

What is claimed and it is desired to secure by Letters Patent is:

l. A chair comprising a base member, a seat 55 member, and a back forthe seat member rising therefrom, one of said members being providedwith iront and rear bearings at each side of the chair and nearer theback of said seat than the 5 front, said other member having at eachside of said seat, oppositely inclined straight line bearing surfacesengaging said bearings, said rear hearing surfaces being of greaterangle to the seat than the front surfaces.

10 2. A chair comprising a base member, a seat member providing a back,said seat member including a front rail and a back rail with a pair ofspaced side rail members on each side thereof extending from one to theother thereby to prol5 vide a pair of guides, a roller mounted by andbetween each pair of side rails in the guides adjacent the centralportion of the seat, and a roller mounted by and between each pair ofside rails in the guides adjacent the rear of said seat, said 20 basecomprising a pair of independent members each having bearing track meansin engagement with said rollers including means comprising oppositelyinclined front and rear bearing portions upwardly extending between saidside rails to be thereby maintained in position by said guides be- 5tween a pair of rollers on each side of said chair.

3. A chair comprising a base, a seat, a back for the seat risingtherefrom, a first pair of rollers fixed to the sides of the seat justforward of the central portion of the seat, and a second pair of 10rollers fixed to the sides of the seat adjacent the rear, said basehaving bearing track means at each of the chair sides in engagement withsaid rollers, said track means comprising oppositely inclined front andrear bearing portions, said rear bearing portions being inclined at agreater angle to the seat than said front bearing portions.
